Karran Quartz Undermount Sink for a Clean White Kitchen

This Karran double-bowl undermount sink brings a crisp white quartz-composite finish to kitchens where the countertop and sink read as one continuous surface. It mounts beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet, with two equal bowls sized to split washing and rinsing duties or keep separate tasks from mixing.

Key Features

• White quartz composite construction with a matte bowl surface that holds color evenly through the body.
• Equal 50/50 double bowl gives two identically sized basins for flexible task separation.
• Undermount installation into granite, quartz, or solid surface countertops, keeping the counter edge uninterrupted above the bowl rim.
• 9-inch inside depth per bowl with a 3-1/2-inch drain opening on each side.
• Requires a minimum 36-inch base cabinet for proper fit.
• cUPC and IAPMO certified for plumbing code compliance.

Two Equal Bowls, One Clean Install

Equal-split double bowls work well when two people share the sink at once, or when the cook wants one side for prep rinsing and the other for washing up. Because this sink undermounts, the counter surface runs straight to the bowl edge with no rim sitting on top, which makes sweeping debris directly into the sink a natural motion and removes a place for water to pool around a drop-in flange. The 9-inch bowl depth on each side handles deep pots and sheet pans without turning into a back strain, and the 3-1/2-inch drain openings accept standard strainer hardware.

White Quartz Composite Inside and Out

The sink is built from a quartz composite material, a dense blend of crushed quartz and resin binders that carries color uniformly through the body rather than just on the surface. White reads as a neutral in nearly any kitchen palette and works as a contrast element against dark stone countertops or as a seamless continuation of a white engineered stone counter. The matte surface keeps the finish from showing water spotting the way a gloss surface would, and the quartz composite body resists the kind of minor surface wear that shows up quickly on lighter finishes in softer materials.

Where This Sink Fits

This is a strong choice for a kitchen remodel or new build where the countertop is being fabricated from quartz, granite, or solid surface. Because it undermounts, the counter needs to be cut and set specifically for this sink, making it the right sink to specify at the countertop-planning stage rather than drop in later. A 36-inch or wider base cabinet is required, and the 32-inch by 19-1/2-inch footprint suits a standard kitchen layout without occupying an oversized run. For designers and cabinet shops specifying complete kitchens, the cUPC and IAPMO certifications keep the install compliant with plumbing codes across most jurisdictions.
